I don't drive this car as much as I used to, but only every now and then. Like todays lunch run. When you finally get the chance and have an eager Z06 driver wanting to run you it's a blast. Now, I didn't win, but he only got 3 to 3.5 car length's on me when he hit 100mph and backed off. By the time I realized he did and let off the gas too, I was by him. I had to be reassured once I got back to the office, that it wasn't bad thing that he beat me. He's twice my displacement and horsepower after all.

Converted the low beam headlights to HID.

Went to the dragstrip this weekend for some fun. This is my best slip. Please take note that the track temperature was about 94 degrees with 54 percent humidity.

  • R/T..... .099
  • 60' ..... 2.362
  • 330..... 6.533
  • MPH..... 55.56

06/21/2010:
I've decided to sell this car.
KBB and Nada put it at $10,545 for a stock version.

This car has several options including Supercharger.
I'm asking $10,500
It has about 50,480 miles on it.
Does not include Sub Box and Amplifiers.

Car has clear title. I expect a bank check that we can go cash before I sign over the title. Either that or cash. Car has factory front end on it at the moment. Car is sold as is, but I'll include the Rieger front bumper and I'll include a fifth wheel which matches the four on the vehicle.

11/23/2010:
SOLD to the gentleman from Boston.

Modifications to date:
Lower radiator hose with a Spectra Stainless Steel one with Pro Hex Clamps. Part numbers SPT39704 and SPT3358B. A Freedom Design Strut Tower Caps and Oil Cap cover. A Freedom Design Strut Tower brace. VF-Engineering Lower Engine Pendulum Mount, also a set of Spectra Bolt Caps. Also, Autometer Nexus Boost Gauge and Steering Column Pod for the interior along with some other items, such as: Varad LED blue replacement bulbs, Superior Dash Silver Armor Carbon Fiber dash kit, Momo Shot Silver shift knob and Ichibahn Track series pedals. Electrical it has a Sun Hi-Rev Hyper Voltage System and a Hyper Ground and a Optima Yellow top battery. Tires and Wheels are Nitto Invo 235/40/18's with 18x8 Ro-Ja / Motegi FF 5 wheels. On the exterior we've added Black Chrome Tail Lamps, Sil Blade Carbon Fiber wiper blades, Rieger R-RX body kit, part numbers we used from Rieger: RIE59017, RIE59013, RIE59030-31, RIE42061, with In-Pro Projection headlights. Bosal supplied us with the exhaust and it has B+G coilovers. There is also complete replacement of the stock component speakers and the addition of subwoofers all JL Audio, with an Alpine deck.

 

GTI VR6 Base Dyno Test Results: [view chart]
The highest stock horsepower we got from our GTI was 173, and the torque was 181. This is average for the car and engine, even though factory listed 200hp. There is always drivetrain loss. A car maker will always gauge power from the flywheel for horsepower and torque ratings. We are running our dynos at the wheel. The average loss of horsepower for front wheel drives is 15%. We had 15% HP loss and 8% in Torque from VW spec's.

GTI Last Dyno Test Results:
Our GTI currently should be around 245Hp and 208 Torque at the wheel or more. If measured from the flywheel it would be around 282Hp and 225 torque. Note: A gain from a modification does not necessarily come at the maximum peak, but can be throughout the power band.

Things I haven't added yet:
APR Wind Splitter Support Rods, Racing Dynamics Short Shifter, Caracter Hatch Spoiler, and Street Glow Light Bars.

Audio:
The stock Monsoon system was ok, but we really wanted to step it up. So, JL Audio products were put in throughout the car. We used a JL Audio 2AWG Wire kit, XR650-CSi 6.5" Component Speakers (2 Sets), CVS312RG-W6v2 Enclosure with (3) 12" W6v2 Subwoofers, and a 300/4 (Components) and a 500/1 Amplifier (Subs). We also added in a Alpine CDA-9835 deck to replace the OE deck. We recorded 146 decibals and still had more to go on the volume.



     

Bling:
Well, not much. We have put chrome strut tower caps and a chrome oil cap in the engine bay. Also there is a billet strut tower brace. That's really about in in the way of chrome and bling. Unless you count the big shiny donut, that is the housing for the supercharger.



     

Brakes:
With all of the performance modifications we are installed, we're going to need some serious stopping power. We went with SP Performance brakes and pads. They make OEM sized slotted, cross-drilled, and diamond slotted brake rotors. We used the cross-drilled and slotted plated rotors front and back. SPP583024F-P and SPP583354F-P are the part numbers. This saved us from having to upgrade calipers, which worked fine, just needed better rotors and pads.



       

Drivetrain:
I blew out the OE clutch. Just couldn't take all the extra power, so it was replaced with a SPEC part SPECSV872 clutch and pressure plate. The OE flywheel looks like a torture device, so out it went and was replaced by a Unorthodox Racing Flywheel. We had fitment issued with another flywheel who shall remain nameless. All of this was done by Metro Volkswagen. Now we have a quick blip of the throttle spins her up quick. There is definitely a difference in the this setup and the stock clutch.



     

Electrical:
A Sun Hyperground system was added to the vehicle. The wiring was ran from the negative to the engine manifold, to the tranny, to the throttlebody, to the far chassis. The other wire was ran from the negative to the drivers chassis. Also, a Sun Hi-Rev Hyper Voltage System was added to the car. All this helped to reduce static in the audio system. It also helps provide better consant spark to the motor. We also added a Optima Yellow top battery for all the power needs.



     

Engine:
The internals are still stock with no modifications. The supercharger hasn't really required any modifications in that way. The supercharger did replace the cold air intake that had been in place. The cold air intake was a Injen INJRD3020, which worked really great. We got a maximum of 10.2 hp and 8.8 torque. You do have to remove the front bumper to install the intake.

We had to replace a radiator hose at one point as it was nicked by the fan blade. That wouldn't have been so bad, except for we were 400 miles from home on the way to a car show. Duck tape and coolant kept us going. We are replaced the lower hose with a Spectra Stainless Steel one with Pro Hex Clamps. Part numbers SPT39704 and SPT3358B.

Injen cold air intake installation information.

Exhaust:
With the Rieger body kit we had to change out the original Bosal Catback exhaust system. We used one of the straight tube dual designs. This allowed us to make the angle custom to match the exit point on the body kit. The original catback was kind of quiet till you romped on it. This new setup is loud and proud. I've had people say it sounds like a fomula one car.

Exterior:
On the rear tail lights we changed them out to some Black Chrome ones and added In-Pro Projection headlights to the front. The body kit is from Germany and is a Rieger R-RX body kit, part numbers we used are: RIE59017, RIE59013, RIE59030-31, RIE42061.



   

Interior:
A Superior Dash kit was install to bling it up some. Instead of the standard billet kits we used the Silver Armor Carbon Fiber, which addes more insterest to the inside. A Momo shift knob was swapped in and some Ichibahn Track pedals. We added a Autometer Boost Gauge and into a steering Column Pod. It's a really great gauge as it has recall function, plus you can set the colors to what you want. We also added Varad LED blue replacement bulbs to the interior light locations.



 

Supercharged Volkswagen VR6
We chose the VF-Engineering supercharger.
Please click here for the Supercharger installation page!

Suspension:
The stock suspension was upgraded early on with B+G Coilovers, they are great set of coilovers and have held up really good. They give a much better feel for the road, but still absorb a lot of the bumps.



     

Wheels/Tires:
I can tell you more than you really want to know about wheels and tires for the GTI. There are a lot of options depending on how you want your ride to look, feel, ride and or perform. I've set this one up more for go than show. It wears 18x8 Motegi FF5 wheels with a +37mm offset. They've held up great and have never failed. Ran through a lot of different tires too. Right now she's wearing Nitto Invo's. These are some really great tires for traction and control. I've squeezed these under the fenders in the 235/40/18 size, which provides more 10mm more width than the 225 and are only about 4mm taller.



     

 



     

Local Places (DFW Metroplex):
I've been asked about where are some good local places for work on your car. Well it's kind of a short list for me, but I've had good luck with the following places: Texas Oil Exchange, Metro Volkswagen, Tom's Southside, Grand Prairie Audio, Craig's Collision, Synthetic Designs and Glacier Tint.
